Description

[0001] The present invention relates to a suturing apparatus comprising a sloped guide,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a suturing instrument used in laparoscopic surgery, and more particularly, to a surgical suturing instrument including a suture portion having an inclined guide so that a living tissue is more easily stitched.

Conventional suturing instruments generally have a needle, a needle pusher portion, and a handle that can be easily operated by a user so that the tissue can be sealed with a suture. When the user actuates the handle, the tissue may be pierced and the suture passed through the tissue and knotted.

However, general suture instruments are structured to require a separate auxiliary mechanism when knotting, and particularly when twisting sutures several times, such as fisherman's knots, there are many levers to manipulate, resulting in inconvenience.

In recent years, suturing apparatuses using needles having a predetermined curvature have been developed as means for overcoming such inconvenience. The suture connected to the needle is pulled after passing the suture through a needle having a predetermined curvature and the pulled suture is positioned at the central portion of the curvature of the needle so that the needle is rotated around the suture so that the suture is easily twisted several times .

For example, U.S. Patent Publication No. 2014-0171977 provides a suturing mechanism using a needle having a predetermined curvature. Referring to Figure 1, there is shown a general configuration comprising an elongated shaft 20, an actuator 10 connected to one end 21 of the shaft 20, and an actuator 20 connected to the other end 22 of the shaft 20. [ And a needle applicator 30 in which a needle is accommodated.

2, the suture portion 30 includes a needle driving portion 70 for driving the needle along the guide groove 55, a link 60 connected to the needle driving portion 70 by a pin 71, a link 60 A pin 62 accommodated in a groove 61 formed in the suture portion 30 and a bent portion 63 which is pivotally supported on the pin 62 as a part of the link 60 and bent to be supported by one side of a step formed on the suture portion 30 A pin 64 accommodated in a slot groove 66 formed in an arm 65 connected to a rotating circular member 67 formed at the end of the link 60 and formed in a rotating circular member 67 And a slot groove 68 for transmitting a driving force.

The sewing mechanism thus configured follows the manner in which the needle driver 70 slides in the groove 55 and the needle is driven by the movement of the link 60 as the circular member 67 rotates.

However, miniaturization of the sealing portion 30 is limited by the inclusion of the rod 60 for the operation of the needle driving portion 70. The end portion of the suturing mechanism to which the suture portion 30 is connected is not free to operate as long as the length of the suture portion 30 occupies. That is, even if a joint is formed on the distal end side of the shaft 20 on which the needle is to be mounted, the distal end of the shaft 20 can be moved only at an interval longer than the length of the sealing portion 30.

 In addition, many components are required to operate in this manner, and the speed and rotational extent of the needle are not controlled. Accordingly, when a large amount of knots is required, the handle must be squeezed a plurality of times, which can easily be fatigued by the user, and the sewing operation speed can also be reduced.

Therefore, at present, there is a need for a suturing mechanism having a suture portion of a size that can be utilized even in a place where the conventional suturing mechanism is difficult to reach due to downsizing and simplification of the constituent elements. In addition, there is a need for a suturing mechanism that includes a suture portion that can control the speed and the degree of movement of the needle easily according to the degree of difficulty of the suturing operation and the situation without limiting the position of the joint that can be formed at the distal end of the shaft.
